playstation 1 games can be used on a ps2 at any time im pretty sure, however the ps1 memory card does not affect this and does not work for a ps2. (as far as i know)
No you cant
Yes, but you cannot save playstation 1 games on a playstation 2 memory card as they are not compatible.
I do believe that a PlayStation 2 will recognize a PlayStation 1 memory card. I use a ps1 memory card in my ps2 might it might vary from the different memory card brands.
yes, as long as its a playstation 1 memory card you are saving to.
There is a silver mad Catz memory card for PlayStation 1 and 2 for sale on amazon used for $12.99 There is also a listing for a Platinum Mad Catz PlayStation Memory card that is no longer available
you need a ps1 memory card
no
yes but only to play a ps1 game
Yes. But you can't save playstation 2 games on it. On a ps2 memory card u can save ps1 and ps2 games
no, mine saved fine when i played it; make sure you have a playstation 1 memory card, not a playstation 2 memory card
You can add 1 account per memory card
The PlayStation 3 has a built in Hard Drive. Ps3 game saves will be saved to the Hard Drive. But to save PlayStation 1 + 2 games, an internal mermory card must be created inside the Hard Drive. PS1 + PS2 games will save there. So no you don't need a memory card for the PlayStation 3.
